16 the World Of Hospitality Aqua flow Suprion Scale Inhibitors - Hard Water Issues Hard water scale deposition will result in potentially expensive and equally important, inconvenient essential maintenance, premature equipment replacement or even a health hazard by creating the areas and nutrients for bacteria to accumulate. Traditional Salt based ion-exchange water softening or some of the more recent innovative media processes are the only guaranteed protection, since comprehensive treatment can be provided at “point of entry”. However, all require space, capital investment, after sales service and management. There may also be logistical and/or practical issues incorporating untreated bypasses for potable applications in commercial situations, albeit essential in conjunction with Laundry/Dish/Glasswashing Machines and/ or steam generating or other comparable total evaporation processes. Selection from alternative wide ranging devices now available can be confusing from over enthusiastic sales claims, inappropriate applications or simply inferior technology and some are seriously expensive with micro processors, programming, commissioning and potential BMS options. In the absence of any empirical evidence or definitive conclusions published by independent recognised bodies, British Gas conducted their own investigative product comparison evaluations several years ago, subsequently endorsed performance of the SUPRION and now installed over 70,000 units for protection of water heating appliances. REFRIGERATOR and been/being fitted in a major high street restaurants throughout the UK during the last 25 years as a economic, practical and effective solution of inhibiting hard water scale related issues in Ice-Makers. These would be the more obvious applications, but ICE-MAKERS and/or REFRIGERATED WATER DISPENSERS have proved extremely successful beneficiaries since the internal areas provide an ideal environment for bacteria if not regularly maintained, de-scaled or appropriate treatment included to the feed water supply; artificially softened water should not be used due to the increased sodium concentration and not therefore compliant with PCV’s {prescribed concentration values). Standard carbon filters will only remove dirt, rust, sediment taste/odour and replacement food grade resin based systems can prove very expensive to maintain a calcium free supply, especially in respect of single feed “self flushing” machines. Following a trial on several banqueting Ice- Makers at The London Hilton back in 1990, the SUPRION was subsequently adopted by FOSTER Website: www.aquaflow.co.uk Tel: +44 (0) 1603 279806 Fax: +44 (0) 1603 277010 [email protected] www.aquaflow.co.uk
